Description:
Bituminous Primers are specially formulated liquid coatings designed to enhance the adhesion of bituminous materials to various surfaces, such as concrete, metal, and masonry. These primers penetrate porous surfaces, sealing them and providing a strong bonding layer for subsequent bitumen applications. They improve waterproofing and surface durability, ensuring long-lasting protection against moisture, chemicals, and environmental stress.
Bituminous Primers are quick-drying and easy to apply, making them ideal for use in road construction, waterproofing, and roofing applications. Their high penetration capability ensures deep surface conditioning, preventing premature failure and enhancing the longevity of pavements and structures.
Available Grades:
- Solvent-Based Bituminous Primer
- Water-Based Bituminous Primer
- Low Viscosity Penetration Primer
Specifications:
- Viscosity at 25°C: 30-300 cSt (depending on grade)
- Drying Time: 30 minutes – 2 hours
- Penetration Depth: 2-5 mm
- Flash Point: ≥ 40°C
- Adhesion Strength: High bonding capability with concrete and metal surfaces
- Standard Compliance: ASTM D41, AASHTO M116
Applications:
- Priming concrete surfaces before bitumen application
- Enhancing adhesion for waterproofing membranes
- Road base and pavement sealing
- Corrosion protection for metal structures
Bituminous Primers play a crucial role in ensuring the durability and effectiveness of bituminous coatings and waterproofing systems. Their superior bonding and sealing properties make them a preferred choice for infrastructure and construction projects, ensuring long-term protection and performance.
